- IANA name:
- TLS_ECDH_RSA_WITH_ARIA_128_GCM_SHA256
- Hex code:
- 0xC0, 0x62
- TLS Version(s):
- TLS1.2, TLS1.3
- Protocol:
- Transport Layer Security (TLS)
- Key Exchange:
- Elliptic Curve Diffie-Hellman (ECDH)
- Authentication:
- Rivest Shamir Adleman algorithm (RSA)
- Encryption:
- AEAD ARIA with 128bit key in Galois/Counter mode (ARIA 128 GCM)
- Hash:
- Secure Hash Algorithm 256 (SHA256)
- Included in RFC:
- Machine-readable:
- application/json
Non-ephemeral Key Exchange:
This key exchange algorithm does not support Perfect Forward Secrecy (PFS) which is recommended, so attackers cannot decrypt the complete communication stream.
RSA Authentication:
There are reports that servers using the RSA authentication algorithm with keys longer than 3072-bit may experience heavy performance issues leading to connection timeouts and even service unavailability if many clients open simultaneous connections.
